" This file is supposed to be saved as "~/.vim/ftplugin/eruby.vim". If desired, parts of it can be

" Surround mappings. The character defines the mapping. Most of these are meant for use in visual

" These ones let you wrap a piece of text on a line with erb <% %> markers. The last one is

Dear Rubyists,

I just lost a contract because of my code in a Rails project.

The specific code in question is related to a "posting a comment" feature. Here are the details:

In this project, "posting a comment" does not simply entail inserting a row into the database. It involves a procedure to yes, insert a row, but also detect its language, check for spam, send emails, and "share" it to Twitter and Facebook. I believe this algorithm should be encapsulated. I do not believe it belongs in a controller or a model. I do not believe Active Record callbacks should be used.

The "senior developer", whom is the stake holder's right hand man, said this:

Berlin Clock

Original Reference

Create a representation of the Berlin Clock for a given time (hh::mm:ss).

The Berlin Uhr (Clock) is a rather strange way to show the time. On the top of the clock there is a yellow lamp that blinks on/off every two seconds. The time is calculated by adding rectangular lamps.

" Put this in plugin/diffsplit.vim.
"
" Executing :Diffsplit on a file, containing a git diff would open up a new
" tab, cd to a temporary directory, and distribute the changes into separate
" files, mirroring the repo layout. You can then use NERDTree or whatever you
" like to browse through the changes.
"
" Using it straight from the command-line is fairly simple and aliasable:
"
"   git diff whatever | vim - -R +Diffsplit
